Sorry about the change in retirement plans. Hope you're doing well. Without knowing any limitations you might have, I would suggest not considering a 5er. We have a disabled adult son and might have considered one but he could not get up and down the steps into the bathroom. Something to consider. I think you're out of luck on the king bed. Can't recall ever hearing about one. The queen size come in the standard household size and also a shorter version. Whatever size you're comfortable with, but the shorter version seems to be more readily available. Many trailers are offering the large "garden shower" with glass enclosure, but not as a tub combo. Also, doubt that you're going to find the residential frig.
I would also agree on the Class C, but if you're interested in day trips in the area, you would have to tow a vehicle and deal with the hitching and unhitching.
Some folks that need a wheelchair or other assistive equipment have gone with a toy hauler and the ramp made access easier. Personal opinion, if you don't need to consider a TH, would be something under 30', 1 or 2 slides, very open floorplan with a large rear window and plenty of light. If you plan to special order, definitely self leveling and any other automatic features you need.
Good luck. Hope you find the perfect trailer and can get out there soon.
